The processing method for stainless steel elbows is as follows:
1. Forging method: The advantage of extending the pipeline by punching is that it can reduce the outer diameter.
2. Stamping method: The tapered core shaft can be expanded to the desired standard size and shape of the tube end on the punching machine.
3. Roller method: A core shaft is placed inside a stainless steel pipe, and a roller can be used to push and process the circular edge from the outside.
